WebInk4 family members inhibit cyclin D by competing for binding to Cdk4 and/or Cdk6. The inhibitors bind Cdk4/6 inducing a conformational change that alters the cyclin binding site [28], therefore, high Ink4 expression blocks formation of the active cyclin D-Cdk4 complex. Because Ink4 prevents cyclin D-Cdk4 complex formation it also prevents ... lambertian sphereWebMar 11, 2024 · CDK4 and 6 control the G1 phase; CDK2 controls the G1–S transition and S phase S; CDK1 controls the M phase. The key regulator of the G1–S transition is the cyclin D–CDK4/6–INK4–Rb pathway.
